Han Sen promised to help Li Keer kill a deified xenogeneic, but Li Keer didn't know where the xenogeneic she needed actually lived. She only knew which system it was said to be in. Han Sen had to go to that system with her.
But this time, Li Keer didn't offer to teach God's Wander to Han Sen first. She was going to wait until Han Sen slew the deified xenogeneic before giving him the final part.
"It looks like Teleport and Galaxy Teleportation were just a down payment." Han Sen wasn't upset about that. It wasn't as if he and Li Keer were family, so this was normal. If Li Keer taught him the skills without anything to gain, he wouldn't know how to repay the favor.
He was chatting with Li Keer on the way, and he was pleasantly surprised to learn that Li Keer was well-educated about most geno arts. In fact, she spoke of many that Han Sen hadn't even heard of. Aside from the woman in Two World Mountain, there was no one Han Sen knew that was as smart as Li Keer.
